Chemical formula of potassium hydroxide: Koh, its solid appearance is white powder or flake, with strong alkalinity and corrosiveness, easy to dissolve in water, easy to absorb moisture in the air to deliquesce or absorb carbon dioxide to generate potassium carbonate, so it can be used as desiccant.
We have heard that potassium hydroxide will appear some black when it is being produced. That's because some of the substances are affected by the production, or there are some problems in the process. But sometimes it will appear red when it is being produced. Why.
The chemical formula of KOH is white powder or flake solid. Its melting point is 380 ℃, and its boiling point is 1324 ℃. It has the characteristics of strong alkali and corrosiveness.
Have you heard that sodium hydroxide can be used to remove a lot of heavy oil substances when it is used, but actually we all know that sodium hydroxide itself is relatively alkaline when it is used, so when it is used, the injuries to hands and other injuries are also serious,
